Effect of Cow Urine on the Growth Characteristics ofFusarium lateritium, an Important Coffee Fungus in Zimbabwe

Abstract

Anin vitroassay was carried out to establish if cow urine at different concentrations (500 µL/mL, 300 µL/mL, 200 µL/mL, and 100 µL/mL) can be used to control the growth ofF. lateritium, the fungal agent causing Fusarium bark disease in coffee. The growth characteristics selected were conidial germination, germ tube length, mycelial growth rate, and sporulation. Copper oxychloride 50% W.P. was the standard, distilled water was the negative control, and undiluted cow urine was the positive control. The undiluted cow urine was most effective in inhibiting fungal growth with the rest of the cow urine concentrations showing dose dependent efficacy compared to the negative control (P< 0.01). Copper oxychloride had the highest efficacy of all treatments with the exception of the inhibition of mycelial growth where undiluted cow urine had higher efficacy and sporulation where efficacy was comparable to undiluted cow urine. There is potential for the use of cow urine as a means of controlling Fusarium bark disease with other advantages being availability, low cost, and limited environmental damage.

In vitro studies of inhibitory activity of plant extracts and cow urine on mycelial growth of stem rot, Sclerotimoryzae of rice

“…cucurbitae (Basak et al, 2002b). In case of F. latinerum causing Fusarium bark disease of coffee, conidial germination, germ tube length, mycelial growth rate and sporulation are suppressed by cow urine (Gotora et al, 2014). 40, 50, 60 and 70 per cent concentration of cow urine suppress sclerotial germination and mycelial growth of S.rolfsii causing foot and root rot of Betel Vine (Amin et al, 2013).…”

Urina de vaca como biopesticida e biorrepelente: revisão sistemática da literatura

“…Assim como para os resultados promissores de estudos sobre a atividade inibitória contra bactérias, observa-se aumento também de estudos trazendo resultados a respeito do potencial antifúngico da urina de vaca (Swami e Alane, 2013;Ashlesha et al, 2013;Gotora et al, 2014). Uma ampla variedade de microrganismos patogênicos tem se mostrado sensível à atividade inibitória da urina de vaca, incluindo espécies de fungos fitopatogênicos (Akhter et al, 2006;Deshmukh et al, 2012;Randhawa e Sharma, 2015).…”
